Impaired proprioception Sensory ataxia 2010-08-18T01:57:54Z SNOMEDCT_US:69131009 Spinal ataxia Incoordination of movement caused by a deficit in the sensory nervous system. Sensory ataxia can be distinguished from cerebellar ataxia by asking the patient to close his or her eyes. Persons with cerebellar ataxia show only a minimal worsening of symptoms, whereas persons with sensory ataxia show a marked worsening of symptoms. HP:0010871 Afferent ataxia SNOMEDCT_US:445458007 UMLS:C0240991 UMLS:C0037921 Afferent (seonsory) ataxia is caused by lackof proprioceptive feedback during gait and stance. It can be caused by lesions to the peripheral nerves, the dorsal root ganglia, or the spinal cord. It can be distinguished from cerebellar ataxia by (1) heavy dependence of the affected individual on visual guidance; (2) a minor degree of oculomotor deficits; and (3) the absence of dysarthria. Afferent ataxia may be associated with impaired tendon reflexes and sensory deficits. Ataxia, sensory
